Application filed April 16, 1910.- Seria'l No. 555,922.

To all whomfit 'may concern:- v

Be 1t' known that we, CHARLES HERBERT DAY and ALBERTDAY, residing, respectively,

at Johns Terrace, Belle Vue Road, Leeds. in the county otYork, England, and

(5 Delph lane, Leeds aforesaid, have inventedlnew and useful-Improvements in or Relating to Packaging andfWrappingMa- 1s a specification.

Thisinvention relates to improvements in packaging and wrapping machines, such as are used for packeting tea, coffee, cocoa, dry

soap, powdered and 'other dry goods, and it is particularly applicable for machines in which bags are used provided with one or more 1nner lining sheets ot'either paper, or lead, or

both, and in which the end of asingle lining 1s. or when two linings a-re employed-an intermediate' and an inner one-the ends are first sepa rated from the outer sheet for closing the end of the bag, by means described in the specification accompanying George Townsends United States application for Letters Patent datedi12th April, 1909, Serial No. 489.403, said'means lcomprising arplate which isl irst inserted between the outer sheet and the lining and afterward causing the plate to be automatically moved outward for partly turning the separated portion of the lining over the contents of the bag. The partly turned over portion is afterward pressed downward by one' or moreatteners. The other portions of the end of' the bag are folded in by ordinary well known means as described in saidapplioation.

For many classes of linedbags the above. described method may be usedwith advantage, butvwhere the outer sheet of 'the bag or its lining' is or are made of thin material then there maybe a difficulty in inserting the separating plate between the outer sheet and the intermediate or other i lining. rllo overcome this ditliculty and-to make the apparatus equally efficientv tor all classes of lined'bags is the object ofthis i invention.

In this invention the ldesired object is achieved by means of a wedge-shapedscpm ratory pivoted to an intermittently vertically reciprocating bar, but arranged-to be pressed inward by a` separately operated runner or bowl for clamping the outer bag against a fixed bracket; Then the-top of the said outer bag isthus clamped, and: before the machines.

wedge-shaped separator has completed: its downward' stroke the lining is pressedin# wai-dover the contents of the bag'by anum ber of needles or pins mounted in an inter imttentA carrier so as to enable the wedge# shaped1 carrier to freely enter bet-Ween the two, and for the lining t0 be afterward closed over by the end ofthefsaid separator when it is moved outward' by a springen the-withdrawal of the runner or bowl.

In the drawings hereunto annexed the' invention isl shown applied to a packaging machine such as is described'in-the specifications of U. S. American- Letters Patents, da-ted 17th November 1903, No. 744,172; dated 21st March 1905, No.` 785,203g5dated v98th April 1908. No. 885,733, and dated' 27th April 1909, No. 919,427, but it may be modilied'so as to be applied to other types or classes of packeting orpackagingor other (Dnly such portions ota pacliaging machine as are necessary to illustrate the application and working of this invention are shown in the accompanying drawings.

As shown at Figs. `13 'and 14'.it .will be noted that the'ilining k'is madeshdrter than the 40 bag in order to enable itA to be morereadily folded in the bag. y.

In the drawings the track cis shown provided with a false bottom-L y 4 All the above named parts may be of a similar construction and operate -in a flike manner to that described in the aforesaidV prior' application.

vTo the side of the track upon which, say,

the filling, creasing'and folding operationsi take' place is fixed a bracket m provided with arecess in whichl a vertical rod n is made to intermittently reciprocate. The vertical rod l is hereinafter termed the lining' carrier rod n. The lower end of carrier rod 'a is connected by a link o to a lever p which is pivoted at its outer and lower end to the stay q. At a suitable distance between the two ends of the' lever p is mounted upon a stud fixed to the said levera runner r arranged to work in thev groove of a cam 19 mounted upon the cam shaft le.. To the upper end of the lining separator carrier rod n is fixed by any suitable means a bracket t' provided with a bifurcated end '1f/Kto which the lining separator 'v is pivoted as shown bracket t.

at Figs. 1 and 4. The lining separator o is constructed as shown at Figs. 15 to 18, that is to say, its lower end fw is enlarged and made wedge-shaped as shown at Figs. 17 and 18, as well as provided on its lower edge with two or more holes or recesses The object of making this edge wedge-shaped is that it may enter between, say the bag j and its immer lining 7c, and as the separator o descends when the rod 11. is caused to travel downward by its cam the inclined portion of the end fw will then force partially over the portion of the lining marked 1 Fig. 10 for fully separating it from the bag. The lining separator u is also provided on its inner vertica surface with a projection y for the reception of a spiral spring .e -which is employed for pressing the separator o outward, as shown at Figs. 4 and 10. Inorder to prevent the separator 'v being moved too far outward its upper surface is provided with va projection 2 which is arranged to come in contact with the upper surfacel ofv the The lining separator o is retained in its inner position (Figs. 1 and 7) against a bracket 3 fixed to the top of the rectangular track @by meansof roller 4 mounted in a`bifurcated carrier pwhich is adjustably fixed in the up er end of a level' 6 fulcrumed to a bracket if fixed to the underside of table b, as shown at Figs. 1 and 4. The roller 4 is made to work down against the incline 20 for ressin the upper end of the bag and the at'sur ace'V of the wedge` shaped ,end w. against the outer surfacey of bracket 3. When the wedge-shaped end w and lining separator v are in the position shown at Figs. 1 and 7 and pressed against bracket 3 theupper portion of the bag y' will be clamped and held securely between the two parts so'as to permit of the hereinafterrdescribed needles 13 pressing gr forcing the upper portion -of inner lining in carries the bifurcated fixing 5 and runner 4 d is moved inward'by cam 9 the lining separator 'a will be' moved inward as shown at Fig. 1, but as soon as the said end of the lever and runner 4 are carried into an out-l ward positiom-as shown at Figs. 4 and 10,-the springe will then cause the lower and wedge-shaped end fw of the lining separator to be moved outward, and in so doing it willV carry the lining-across the contents at the mouth of the bag, and thus fold it inward as shown in said figures. The cam 19A is so formed that the lining separator 'u is caused to descend for pressing the folded portion of the inner lining down\vard,- after vbeing folded over,--into the contents of the bag, and the thickened upper and side portions -of the separator also kink or crease the' lining so as to prevent it from springing upward when the pressure is removed.

In order. to first separatethe lining c from the bag 7' afterfthe wedge-shaped end fw of the lining separator enters the bag a horizontal reciprocating 'carrier 10 (Figs. '23 and 24) is provided' and arranged to work in the boss ofa bracket 11 which is `fixed to the side of guide bracket mi as shown at Figs. l, 4 and 7. The carrier 10 is provided .With a cross piece`12 at its inner end having -a number,-say for example, two,-pins 13 which are arranged to pass through the recesses a in the lower edge of the wedgeshaped end w of the lining separator e, and

also through the opening 14 in the bracket 3. This permits of the carrier l() working in the center of the box, and the carrier rod two or more li-ni n will require to be slotted forv the passage of carrier 10. An intermittent reciprocating mot-ion is imparted to the carrier 10 by means of a lever'16,-to which the said carrier is attached,fulcrumed to a bracketl'? fixed to the underside of the table b. The lower end of lever 16 is provided with a runner IS-a'dapted to work in the vgroove of cam s which is mounted upon the cam shaft z.

In the drawings a bag j is' shown with one lining r, but it will readily be understood gs may be employed. if so desired.

The action of the apparatus is as follows ;-The boxes z' having been placed in position inthe track, c, a lined bag j with one of its ends already folded and closed is placed in one of the traveling boxes i with its mouth in an upward and open position as shown in the drawings. been filled inthe usual manner with the measured contents to be inclosed, the box is moved intoposition for vthe open mouth of the bag to befolded. When the bag reaches this position the lining separator a will be raised' to its highest position and clear of the top of the open mouthed bag. The lining separator r is then moved downwardby means of cam 19, lever p .and link o until its inner end is within thebag and has been forced against. the bracket 3 by roller 4 being moved inward by cam 9 and lever (i. The lower wedge-shaped end w of the lining separator i: is enabled to first grip the bag j owing to the lining being madef-as previously described,-sl1orter in length than said bag, simultaneously with The bag having tween the inner surface of the bag and theouter surface of the lining and said pins hold the upper portion of the lining` in the position shown until the lining separator 'u has completed its downward stroke. lVhen the said downward stroke has Vbeen completed the runner 4 will be moved by lever 6 and cam 9 to its outward posit-ion as shown at Figs. 4 and 10, and as soon as the pressure of the runner 4 is removed from the end of the lining separator c the spring .e -will expand and move .the said separator into its outer positionas shown at Figs. 4 and 10 and in so doing the upper end of lining L will be carried horizontally across the contents of the bag. The lining separator o, needles 13, carrier 10 and carrier rod a are afterward raised clear of the bag and returned by their respective cams and levers to their upper or outward and normal positions.

By the herein described means one portion of the lining is first separated from the upper portion of the bag and separately folded over the contents of the bag` afterward the lining and the bag on the opposite side are folded 'simultaneously over the fold of the lining and subsequently and successively the end lugs or opposing upstanding ends of the bag and its lining which will have been formed, .are folded before the remaining upstanding portion' of the bag y', from which the lining has been separated, is folded down into position. When it is required to open the bag it will be found thatthis method of folding permits the folds of the bag and its lining being opened without disturbing the first folded portion of the lining, thereby providing a tight bag from 'which its contentscannot escape.
